I notice some sellers appear to have Multiple listings for the same identical item although the content of the Title differs. Eg I am in the Auto sector and 1 part may have multiple applications. Eg fits a Toyota Landcruiser and a Toyota Camry. For search purposes the listing Title needs to be different. My question is How do you set up these listings so the stock quantity is altered from which ever listing is sold? Note "Variations" in this Sector are not available (from what I can see) and not the best solution. Any assistance would be appreciated.
